What was the temperature in Antarctica?
The average annual temperature ranges from about −10°C on the Antarctic coast to −60°C at the highest parts of the interior. Its immense ice sheet is up to 4.8km thick and contains 90% of the world’s fresh water, enough to raise sea level by around 60 metres were it all to melt.
What is the warmest temperature Antarctica has ever been?
18.3C
The hottest-ever temperature recorded in Antarctica has been confirmed by leading climate scientists with the United Nations. The temperature of 18.3C in the southern polar region, one of the fastest-warming places on the planet, was announced by the World Meteorological Organisation (WMO).
What was the average temperature in Antarctica 90 million years ago?
The outcomes suggest that the annual mean air temperature was around 12 degrees Celsius. Average summer temperatures were around 19 degrees Celsius; water temperatures in the rivers and swamps reached up to 20 degrees, and the amount and intensity of rainfall in West Antarctica were similar to those in today’s Wales.
When was Antarctica warm?
The Cretaceous, 145m to 66m years ago, was a warm period during which Earth had a greenhouse climate and vegetation grew in Antarctica. Scientists say the new discovery not only reveals that swampy rainforests were thriving near the south pole about 90m years ago but that temperatures were higher than expected.
When was the hottest day ever recorded in Antarctica?
The record for the Antarctic region as a whole, including all ice and land south of 60° latitude, was 19.8C, taken at the UK’s Signy Island station in January 1982.
Do any animals live on Antarctica?
Antarctica’s wildlife is diverse and unique. It is the only continent on Earth which has no terrestrial mammals, but is home to a range of marine wildlife and birds, including penguins! The most common birds in Antarctica are penguins. It is home to 18 different species, including the Emperor Penguin.
What was the temperature on Earth when dinosaurs lived?
“Our results demonstrate that dinosaurs in the northern hemisphere lived in extreme heat, when average summer temperatures hovered around 27 degrees [Celsius]. As such, one can well imagine that there were summer days when temperatures crept above 40 degrees.
What was Antarctica like millions of years ago?
Sediment analysis from a layer deep within the Earth revealed that the dirt had first formed on land, not the ocean. A new paper reveals that the frozen continent of Antarctica was once a temperate rainforest.
What is Antarctica’s warmest month of the year?
January
January is the warmest month in Antarctica, when average temperatures climb all the way up to 0ºC (32ºF) in the Antarctic Peninsula. However, average temperatures range from -10ºC to -60ºC (14ºF to -76ºF), depending on how far into the continent you travel.

How is the climate in Antarctica in the last 50 years?
The continent-wide average surface temperature trend of Antarctica is positive and significant at >0.05 °C/decade since 1957. The West Antarctic ice sheet has warmed by more than 0.1 °C/decade in the last 50 years, and is strongest in winter and spring.
What was the average temperature in Antarctica in 1982?
A higher temperature of 19.8 °C (67.6 °F) at Signy Research Station on 30 January 1982 is the record for the Antarctic region encompassing all land and ice south of 60° S. The mean annual temperature of the interior is −57 °C (−70.6 °F).
What’s the average temperature at Casey Station Antarctica?
Oddly, the average temperature at Casey Station reaches its minimum of -15 °C (5 °F) in May, probably for the change in atmospheric circulation that occurs in winter, while it peaks around -0.5 °C (31.5 °F) in January.
Which is the warmest part of Antarctica in the summer?
The coast is warmer; on the coast Antarctic average temperatures are around -10°C (in the warmest parts of Antarctica) and in the elevated inland they average about -55°C in Vostok. . Along the Antarctic Peninsula, temperatures as high as 15 °C (59 °F) have been recorded, though the summer temperature is below 0 °C (32 °F) most of the time.
